i noticed alot of cooling fan problems,a freinds ds seemed like the fan ran all the time last time we went riding,second day he added some 40 below to the cooling system and we hardly notice the fan running at all.he also uses it in a race truck,the stuff seems to drop the temp by quite a bit.i think he said 30-40 degrees

 

hey, how much of that 40 below would you add to the radiator to make it cool the best without ruining the cooling system (if that is possible) Thanks

I just got my 40below today in the UPS.
I got it from Jegs.

Oh yeah, I much did you friend add? Did he just pour it in as is to the coolant mixture percentage from the factory?
thanks,

 

i think he added what it said on the can.i dont think it was all that much because i think a can will do a car cooling system.
